HIRAM H. SPONENBURG, OF WADSWORTH, ILLINOIS, ASSIGNOR OF ONE- HALF TO EDWARD LAAs, OF OTTUMWA, IowA.

RAILWAY-RAIL STAY.

SPECIFICATION forming part of Letters Patent No. 792,800, dated June 20, 1905.

Application filed October 8, 1904. Serial No. 227,684.

To all whom, it may concern:

Be it known that I, HIRAM H. SroNnNnURe, of Wadsworth, in the county of Lake, in the State of Illinois, have invented new and useful Improvements in Railway-Rail Stays, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to devices designed IO to prevent longitudinal creeping of the rails of railways.

The object of the invention is to provide a rail-stay which shall be strong, durable, and efiicient in its operation without danger of 5 weakening the rail and shall be conveniently applied to the rail; and to that end the invention consists in the improved construction and combination of the component parts of the rail-stay,as hereinafter described, and summed up in the claims.

In the accompanying drawings, Figure 1 is a transverse section of a railway rail equipped with my improved rail-stay. Fig. 2 is a side View of the same. Fig. 3 is a trans- 5 verse section on the line X X in Fig. 2. Fig.

4 is an inner end view of one of the rail-gripping jaws, and Fig. 5 is a detached isometric View of said rail-gripping jaw.

Similar letters of reference indicate corre- 3 sponding parts.

Rdenotes the railway-rail, and B represents one of the cross-ties which support the said rail.

a and (0 represent the jaws which grip the flange-s 7) b on the base of the rail. Each of the aforesaid jaws is formed with a horizontal ledge c, which extends from the back of the jaw and has depending from it the vertical breast (Z, which abuts 0n the side of the cross- 4 tie B to resist the tendency of longitudinal creeping of the rail R.

e c are two vertical walls which project at right angles from the breast (Z and to the under side of the ledge 0. Each of the walls a c is provided with suitable bolt-supports, preferably holes ff, which are in line with each other and parallel with the bottom of the rail R.

der each o'f'the aforesaid gripping-jaws, passes 5 a bolt /1., which is provided on its ends with suitable means for drawing the jaws into gripping position, for which purpose I prefer to provide the bolt /2. with a head vi on one end and a nut a on the opposite end, as shown.

To impart ample rigidity to the walls a e,

I unite them by means of vertical braces e 6, extending from wall to wall and to the bottom portion of the jaws and ledge c.

In order to cause the rail-gripping jaw to obtain a more secure hold on the rail, I form the interior of the jaw with minute ribs 4' 0', which are disposed in lines at right angles to the rail, so as to cause said ribs to cut their ways in the surface of the base of the rail in S forcing the jaw into gripping position. Inasmuch as the flange of the rail is usually beveled on its top and the interior of the jaw is correspondingly beveled, said flange becomes wedged in the jaw and the ribs 0 a are caused 7 to more effectually embed themselves in the base of the rail.

What I claim as my invention is 1. A railway-rail stay consisting of railgripping jaws sustained movably in a line parallel with the bottom of the rail and provided with a breast bearing on the side of the crosstie and with walls projecting from said breast and formed with bolt-supports in line with each other and parallel with the bottom of the 30 rail, and a bolt passing through said supports and provided with means for d rawing the jaws into gripping position.

2. In a railway-rail stay, a jaw gripping one of the flanges of the rail, a horizontal ledge extending from the back of the jaw, a vertical breast depending from said ledge and extending lengthwise thereof and walls projecting at right angles from the breast and to the ledge and provided with bolt-holes in line with each 9 other and parallel with the bottom of the rail, as set forth.

3. In a railway-rail stay, a jaw gripping one of the flanges of the rail, a horizontal ledge extending from the back of the jaw, a vertical breast depending from said ledge and extending lengthwise thereof and walls projecting at Through the holes f f of the walls 0 6, un- I right angles from the breast and to the ledge and provided with bolt-holes in line with each other and parallel with the bottom of the rail, and braces connecting the edges of said Walls to each other and to the ledge, as set forth.

4:. The combination, with the rail provided with flanges on its base, of jaws gripping said flanges and provided internally with ribs disposed in lines at right angles to the rail to cut their ways in the surface of the base of the rail in forcing the jaws into gripping position as set forth.

5. A railway-rail stay consisting of jaws gripping the flanges of the rail and provided on their bottom gripping-faces with ribs disposed in lines at right angles to the rail, ledges extending from the backs of the jaws, breasts depending from the ledges, walls projecting at right angles from the breasts, and provided with holes in line with each other and parallel with the bottom of the rail, and a bolt passing through the aforesaid holes and provided with means for drawing the aws into gripping position, as set forth.

6. A railway-rail stay consisting of jaws gripping the flanges of the rail and provided on their bottom gripping-faces with ribs disposed in lines at right angles to the rail, ledges with means for drawing the jaws into gripping position, as set forth.
